Unless you want to invoke the wrath of Han, don't ask Harrison Ford about "Star Wars."

Only recently -- since über-director J.J. Abrams confirmed he was helming the sequel, "Star Wars: Episode VII" -- has the actor expressed much enthusiasm about his iconic character in the franchise, beloved mercenary Han Solo.

On "Jimmy Kimmel Live" Wednesday, Ford riffed on the secrecy surrounding the movie (with rumors swirling that Ford, Carrie Fisher and Mark Hamill might reprise their original parts) and his historical reluctance to discuss his breakout role.

He flatly refused to discuss the new film during the interview, and when his host asked whether he'd take audience questions, Ford agreed -- on one condition: "No 'Star Wars' questions."

Of course, every person who took the microphone was outfitted in a "Star Wars" costume -- and thrown off-guard by the actor's mandate. Obi-Wan Kenobi stuttered, "Do you like being in movies?" A bearded dude dressed as Princess Leia asked an even more mundane question: "Are you hungry?"

But Chewbacca refused to play ball. His comments, spoken in his native Wookiee language (Shyriiwook, to be precise), enraged his former co-star.

"You son of a b----," Ford snarled, as the audience roared in laughter. "What do you want?"

"Yeah, you'd like that wouldn't you?" he said after Chewy's next remark. "Always trying to blame me. You're the one who couldn't keep it in your furry pants!"

In a profanity-laced faux tirade, Ford accused Kimmel of engineering the showdown with the creature who betrayed him.

"He knows what he did. She was my wife! You Wookiee (expletive)."

Finally, Ford couldn't take it anymore and stormed off the set.

"I'm out of here," he said, with one parting message to his former co-pilot.

"You -- I'll see you in hell!"

Let's hope they patch things up, because actor and comedian Patton Oswalt features them prominently in his epic eight-minute "Star Wars" filibuster. The eight-minute outtake of his rant, featured Thursday night on NBC's "Parks and Recreation," hit nearly 1 million YouTube views in a single day. In his suggested storylines for the franchise sequels, he includes this gem featuring Kimmel's guests:
